Jens Axboe 9f4107b07b block: store bdev->bd_disk->fops->submit_bio state in bdev 
We have a long chain of memory dereferencing just to whether or not
this disk has a special submit_bio helper. As that's not necessarily
the common case, add a bd_has_submit_bio state in the bdev to avoid
traversing this memory dependency chain if we don't need to.
